Calculate the line voltage for 3-∅ 120° VSI if the value of DC supply is 24 V.(a) 16.52 V(b) 16.97 V(c) 12.96 V(d) 12.48 VI got this question in my homework.My doubt stems from Solid-State Switching Circuits topic in section Introduction to Solid-State Switching Circuits of Electric Drives |

Answer» RIGHT OPTION is (B) 16.97 V To elaborate: The line voltage for 3-∅ 120° VSI is (VDC÷√2)=.707×24=16.97 V. In 3-phase 120° VSI each phase conducts for 120° and only three SWITCHES from DIFFERENT phases conduct at a single time. |
